“…Menn et al (2007) relataram que, na fase de alvéolo cortical, se inicia a inclusão de vitelogenina no citoplasma do ovócito. Semelhante ao que ocorreu com Danio rerio (Yön et al, 2008), com o avanço da fase de alvéolo cortical o nú-cleo dos ovócitos de M. boesemani se tornou disforme e com aspecto opaco, até praticamente desaparecer em meio aos alvéolos, concomitantemente, a zona radiata se tornou mais visível e espessa, assim como relatado por Jiang et al (2010).…”

Resumo: Estudou-se o tecido germinativo ovariano do peixe Melanotaenia boesemani. Por meio de análises morfológicas das gônadas, realizadas após a confecção de lâminas histológicas elaboradas em parafina e coradas com hematoxilina-eosina, foram descritos os tipos celulares encontrados e realizada a classificação do estádio de maturidade dos peixes. Macroscopicamente, foi identificado que a referida espécie possui ovário único, arredondado e, na fase observada, amarelado, localizado na parte látero-anterior da cavidade celomática. As fêmeas analisadas foram classificadas na escala de desenvolvimento gonadal como maduro/em reprodução. A presença de folículos vazios e marcas de desova nas lamelas ovulígeras mostrou-se evidente. Nos ovócitos vitelogênicos deste peixe, foi constatada a presença de filamentos de adesão ovocitária ancorados à zona pelúcida. Os ovários apresentaram aspecto morfológico geral semelhante ao de outros peixes teleósteos. Seu tipo de desova foi classificado como intermitente e o padrão de desenvolvimento de ovócitos, como assincrônico.

“…To facilitate such development a number of evolutionary adaptations exist that counteract adverse environmental effects and favour factors beneficial to the developing embryo (e.g., factors affecting suitable spawning time, spawning performance, nest construction, egg deposition, parental care, and egg structure) (Depêche and Billard 1994, Chen et al 2007, Fava and Toledo-Piza 2007, Fishelson and Gon 2008, Jiang et al 2010.…”

“…Additionally, the egg is covered by a limp, delicate, gelatinous coat that surrounds the egg by the end of oogenesis and after its discharge form the oviduct. The size, shape, and the weight of egg cells are determined by their taxonomic affiliation (Riehl and Schulte 1977, Riehl 1978, Mikodina 1987, Britz and Bartsch 1998, Britz and Cambray 2001, Bless and Riehl 2002, Depêche and Billard 1994, Fausto et al 2004, Chen et al 2007, Fava and Toledo-Piza 2007, Fishelson and Gon 2008, Jiang et al 2010.…”

“…The gelatinous layer-distinct in some teleost fishes-is usually formed between the radial layer of the egg shell and the follicular cells of the ovary follicle and has been treated as an amorphous structure (Bonsignorio et al 1996, Jiang et al 2010) It contains high amounts of glycoprotein (Kobayashi 1982, Scapigliati et al 1995, Chiou et al 2004 as occurs also in the zona radiata externa (Mansour et al 2009). Immediately after the egg deposition this gelatinous substance quickly acquires water and swells.…”

“…While in water, perch eggs form a gelatinous structure, which is greatly enhanced by ovarian fluid (Mansour et al 2009). Similar, although not identical gelatinous envelopes are produced in the eggs of many other teleost fish species such as: vimba, Vimba vimba (L.); lumpsucker, Cyclopterus lumpus L.; white bream, Blicca bjoerkna L.; Chinese perch, Siniperca chuatsi (Basilewsky, 1855); spirlin, Alburnoides bipunctatus (Bloch, 1782); and roach, Rutilus rutilus (L.) (see: Davenport and Lonning 1983, Patzner and Glechner 1996, Britz and Bartsch 1998, Szulc 2007, Jiang et al 2010.…”

Formicki K., Smaruj I., Szulc J., Winnicki A. 2009. Microtubular network of the gelatinous egg envelope within the egg ribbon of European perch, Perca fluviatilis L. Acta Ichthyol. Piscat. 39 (2): 147-151.Background. After their deposition in water, eggs of perch form characteristic, long gelatinous ribbons (strands) floating within the water column. The ultrastructure of the external gelatinious egg envelope of members of the family Percidae was believed to be amorphous. The aim of the presently reported study was to describe the ultrastructure and function of the gelatinous egg envelope composing the perch egg ribbon. Materials and Methods. Fresh eggs of European perch, Perca fluviatilis L., were collected, in the form of egg ribbons, from females caught at the spawning grounds on the Odra River side canal Dziewoklicz, within the city limits of Szczecin, Poland. After fertilization eggs were fixed in 4% formaldehyde. In the laboratory, the commonly accepted techniques (dehydration, critical-point drying, sputter coating) were used to prepare samples for examination with a scanning electron microscope (SEM). The observations were photographically documented.Results. Closely below the surface of the gelatinous egg ribbon we observed a network of microtubules. These microtubules opened at the egg ribbon surface in the form of ring-like or nozzle-like pores. Conclusion.The gelatinous egg envelope of perch is a complex microtubular network that likely performs a skeletal role for the egg ribbon. Our results also suggest that the regular surface openings of the aforementioned network may play an attachment function (micro-suckers) reciprocally between eggs and between eggs and other objects, thereby facilitating the fastening the eggs to underwater vegetation.
